1. Connect the sensor to the interface (LabQuest Mini, LabQuest 2, etc.).
2. Start the appropriate data-collection software (Logger Pro, Logger Lite, LabQuest App) if not already running, and choose New from File menu.

The software will identify the sensor and load a default data-collection setup. You are now ready to collect data.

If you are collecting data using a Chromebook™, mobile device such as iPad^® or Android™ tablet, or a Vernier wireless sensor or interface, please see the following link for up-to-date connection information:

www.vernier.com/start/tmp-bta

Connect the sensor following the steps in the Getting Started section of this user manual.

Here are some general guidelines for usage:

• The probe handle is constructed of molded plasticized Santoprene^®. While this material is very chemical resistant, we recommend that you avoid submerging the probe beyond the stainless steel portion.
• Always wash the probe thoroughly after use.

Temperature range	–40 to 135°C (–40 to 275°F)
Maximum temperature that the sensor can tolerate without damage	150°C
13-bit resolution	0.09°C (–40 to 0°C) 0.02°C (0 to 40°C) 0.05°C (40 to 100°C) 0.13°C (100 to 135°C)
12-bit resolution	0.17°C (–40 to 0°C) 0.03°C (0 to 40°C) 0.1°C (40 to 100°C) 0.25°C (100 to 135°C)
10-bit resolution	0.68°C (–40 to 0°C) 0.12°C (0 to 40°C) 0.4°C (40 to 100°C) 1.0°C (100 to 135°C)
Temperature sensor	20 kΩ NTC Thermistor
Accuracy	±0.2°C at 0°C, ±0.5°C at 100°C
Response time (time for 90% change in reading)	10 seconds (in water, with stirring) 400 seconds (in still air) 90 seconds (in moving air)
Probe dimensions	Probe length (handle plus body): 15.5 cm Stainless steel body: length 10.5 cm, diameter 4.0 mm Probe handle: length 5.0 cm, diameter 1.25 cm

This probe uses the 20 kΩ NTC Thermistor, which is a variable resistor. When the temperature increases, the resistance decreases non-linearly. The best-fit approximation to this nonlinear characteristic is the Steinhart-Hart equation. At 25°C, the resistance is approximately 4.3% per °C. The interface measures the resistance value, R, at a particular temperature, and converts the resistance using the Steinhart-Hart equation:

T = [K₀ + K₁(ln 1000R) + K₂(ln 1000R)³]^-1 – 273.15

where T is temperature (°C), R is the measured resistance in kΩ, K_o =1.02119 × 10 ^-3, K₁ = 2.22468 × 10^-4, and K₂ = 1.33342 × 10^-7. Our programs perform this conversion and provide readings in °C (or other units, if you load a different calibration).

In most cases, the Stainless Steel Temperature Probe will not need to be calibrated. It is calibrated before it ships. However, you can calibrate the sensor using Logger Pro 3.3 or newer. Note: Calibration can only be done on computers running Logger Pro. For more information, see www.vernier.com/til/1310

The most common causes for this sensor to break are

1. Twisting the cable. Sometimes students twist or crimp the wire near the handle of the sensor. Over time, this can cause the wires to come loose and make the sensor stop working.
2. Overheating the sensor. When used in chemistry labs, students will sometimes lay the sensor on a hot plate and effectively "cook" the unit.
3. The unit is not waterproof! Water can seep into the hilt of the sensor and damage the electronics. Only submerge the stainless steel portion the sensor into water when collecting data.

Unfortunately, these causes of breakage are considered misuse and are not covered by our warranty. In our experience, repair is not possible for this type of damage.

The Stainless Steel Temperature Probe body is constructed from grade 316 stainless steel, which provides a high level of corrosion resistance for use in the science classroom. Here are some general guidelines for usage:

• The probe can be left continuously in water at temperatures within the range of –40 to 150°C. Continuous usage in saltwater will cause only minor discoloration of the probe, with no negative effect on performance.
• You can leave the probe continuously in most organic compounds, such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, n-hexane, lauric acid, paradichlorobenzene, phenyl salicylate, and benzoic acid. The probe should not be left in n-pentane for more than one hour.
• The probe can be left in strong basic solutions, such as NaOH, for up to 48 hours, with only minor discoloration. We do not recommend usage in basic solutions that are greater than 3 M in concentration.
• The chart provides the maximum length of time recommended for probe exposure to some common acids. Probes left in an acid longer than these times may bubble and/or discolor, but will still be functional. We do not recommend probes be left to soak in any acid longer than 48 hours.

Maximum acid exposure time
1 M HCl	20 min
2 M HCl	10 min
3 M HCl	5 min
1 M H2SO4	48 hours
2 M H2SO4	20 min
3 M H2SO4	10 min
1 M HNO3	48 hours
2 M HNO3	48 hours
3 M HNO3	48 hours
1 M CH3COOH	48 hours
2 M CH3COOH	48 hours
3 M CH3COOH	48 hours
1 M H3PO4	48 hours
2 M H3PO4	48 hours
3 M H3PO4	48 hours

Primary Test

Follow the steps in the Using the Product section. Hold the tip of the sensor in your hand and check for a change in the temperature readings.
